Subject: 10% of all Module::Install-driven CPAN dists have wrong version in META.yml
Download (untitled) / with headers
text/plain 490b
The attached file lists all Module::Install-driven distributions at CPAN which seem to have a wrong version in their META.yml. It looks like this problem systemically happens because META.yml is only regenerated when inc/ is recreated, but this is not forced in any phase when building the distribution package (unlike in EUMM, where META.yml is generated right before creating the distribution package). I stumbled over this problem in my own distro Image-Info-1.30. Regards, Slaven

Hi. Thanks for the list. It'd help us much when we urge early users to upgrade Module::Install in the future. However, the problem is not Module::Install doesn't recreate META.yml while packaging. In fact Module::Install recreates it each time a distribution author runs "perl Makefile.PL" (if the META.yml is created automatically by Module::Install). The real problem is packaging/releasing by someone other than the author (at least for Module::Install, which checks inc/.author directory to see if they are authors or not). This happens most probably because an inc directory created by the original author is included in a distribution's repository (except for the hidden inc/.author). In this case, what they check out looks the same as what they download from CPAN, thus Module::Install won't try to recreate META.yml etc, and then *kaboom*. Maybe a piece of documentation would help a bit, and it's not that hard to check version integrity while running "perl Makefile.PL", but I think this needs to be discussed further.

Hello ISHIGAKI, I have to disagree. Traditionally (that is, when using stock EUMM), META.yml is only created when doing "make dist". I think this should also happen with Module::Install. No additional documentation necessary, everything's working out-of-the box, no problems when authors change. Regards, Slaven Show quoted text

I ran into this issue today too in one of my program. My META.yml had been out of sync for the last few releases. I tried 'perl Makefile.PL' but it did not help. 'make dist' did not help either, in that possibly it created the new META.yml in the tarball, but not in my current directory. I had to remove inc and run 'perl Makefile.PL' to have the META.yml be regenerated and up-tp-date.
